Abstract

The character of the interaction in the As2Te3-TlSe system was studied by the methods of Differential Thermal Analysis (DTA), X-ray Diffraction (XRD), Microstructure analysis (MCA), and also by measuring the microhardness and determining the density of alloys, and state diagram was constructed. It is established that the As2Te3-TlSe state diagram is a quasibinary section of the triple mutual system As, Tl // Se, Te. Two new compounds, TlAs2Te3Se and Tl3As2Se3Te3, are formed in the As2Te3-TlSe system. Both compounds are obtained in the vitreous state. Solid solutions based on As2Te3 at room temperature reach up to 3 mol.% TlSe, and based on TlSe-2 mol.% As2Te3. The electrical conductivity and thermoelectric power coefficient of the (As2Te3)1-x (TlSe)x solid solutions have been measured as functions of temperature.
